Research on Rational Utilization of Urban Water Resources Based on Sponge City Theory-Making Comparison between China and Singapore

Water resources are indispensable for human survival and production activities, but the world's per capita sharing of water resources are not optimistic. With the acceleration of social development and industrialization, people pay more attention to economic development than the protection of water resources. Water pollution and waste have also worsened the issue of water scarcity. China, as the most populous country in the world, is particularly struggling for water shortage. Therefore, the research on the rational use of water resources is of great significance to China's sustainable and healthy development. This paper analyzes the difficulties of water resources utilization and the issue of under-utilization of domestic water resources in China. It then accordingly proposes recommendations by comparing the current situation of sponge city construction at home and abroad. It is found that we are now facing the difficulties of water shortages, water resources waste and pollution in China on water use. What's more, the fact that sponge city construction is mainly carried out in emerging cities indicates that we can learn from the successful experience of other countries like Singapore to make overall planning for regions and by time according to the national condition of China. Specifically speaking, the problems concerning water resources in different cities will be solved based on their local conditions.
